The first research research on Apple's Health Records service has just been released and shows that users have a favorable view of its capabilities, though it hasn't been widely adopted.

Researchers at the University of California San Diego Health, one of the first health systems to integrate with Apple's health service, spent a few months surveying patients about the technology, and published the results of their research on Friday in the Journal of the American Medical Association (JAMA). UCSD is among dozens of hospitals working with Apple, letting any patient with an iPhone use the health app to view their labs, charts, immunizations and more.
